12 Claims.

Our invention consists in a novel and efficient method for attaching endsheets to book bodies which have been previously provided with hingestrips having overlapping and free portions, said method including,generally, the following steps:

advancing successive book bodies along a suitable support, gummingportions along the two leaves of a folded end sheet and adhering thegummed portion of one leaf to the overlapping portion of a hinge stripon one side of a book body, folding the free portion of the hinge stripover onto the gummed portion of the other leaf of the folded end sheetand adhering it thereto.

Our method may also include the reversing of each book body after thefolded end sheet has been secured to one side thereof and conveying saidbook body intoV position where the successive steps may be employed forrepeating the folded end sheet attaching operations on the opposite sideof each book body.

Our invention more specifically comprises in one instance, the gummingof the leaves of a folded end sheet along opposite sides of the foldedouter edge of the sheet, and in another instance the gumming of theleaves along the free edges thereof.

Our invention further comprises, in one instance, the gumming of narrowand wide portions on the leaves along the opposite sides of the foldedouter edge of the folded end sheet so that the narrow gummed portion ofone leaf may be adhered to the narrow overlapping portion of a hingestrip and the wide free portion of the hinge strip may be adhered to thewide gummed portion of the other leaf.

Our invention further comprises, in another instance, gumming narrowportions along leaves of an off-middle folded end sheet whereby thenarrow gummed portion along the wide leaf may be adhered to the narrowoverlapping portion of a hinge strip and the wide free portion of thehinge strip may be adhered to the narrow gummed portion of the narrowleaf.

Our invention further comprises the sir-nul-` taneously gumming ofportions along the leaves of a folded end sheet either upon oppositesides of its folded edge in one instance orV along the free edges of theleaves in another instance.

A machine for carrying our method is shown and described herein,- saidmachine forming the subject matter of our copending application filed ofeven date herewith, its Serial No. being 363,285.

The book bodies I are each provided on both sides with hinge stripswhich are shown herein 45 as-having narrow overlapping attached portions2 and wide free portions 3.

The end sheets are shown in one embodiment as folded in the middle toform equal width leaves 4 and 5 and in the other embodiment as 50 foldedoff the middle to form wide and narrow leaves 6 and 1 respectively. Itis understood that the leaves 4 and 5 of the middle folded end sheetsare intended to be adhered along their outer faces on opposite sides ofthe fold to the free edge of middle folded end sheets may be providedwith narrow and Wide bands 8 and 9 respectively of gum upon oppositesides of the fold, and thev outer faces of the leaves 6 and 1 ofthe-off-middle ,y folded end sheets may be provided with narrow bands I0and I I respectively of ggum'alongy their free edge portions; it Ibeingunderstood that in this latter instance the folded edge of the end sheetmay |be subsequently trimmed with the edges of the book body, to formtwo separated leaves. Y

The machine comprises, generally, a supporting table; means forsupplying successive book bodies provided with hinge strips; means forintermittently advancing the book bodies successively from theirmagazine; means for supplying folded end sheets for attachment tothehinge strips on one side of the book bodies; means for applying gum,preferably, simultaneously, `to the outer faces of the leaves of thefolded end sheetsl along the desired portions thereof; means for foldingthe free edges of the hinge strips over onto the'gummed portions of theupper leaves of the folded end sheets after the gummedportions of thelower leaves have been applied to the overlapping attached portions ofthe hinge strips; and means for applying sealing pressure to ensure acomplete attachment of the end sheets to the hinge strips.

Where it is desired to attach the foldedl end sheets to the other sideof theV book bodies by other apparatus in the same machine, the'machinewill include beside the meansv already set forth: means for reversingthe book bodies and means for conveying the reversed book bodies intoposition to have the folded end sheets attached to their other side; itbeing understood `that in this instance there are provided: a secondmeans for advancing the book bodies; a second means for supplying foldedend sheets; a second means for applying gum, preferably, simultaneously,to the outer faces of the leavesA of the folded end sheets; a secondmeans for folding the free edges of the hinge strips over onto theexposed gummed portions of the upper leaves of the folded end sheetsafter the gummed portions of the lower leaves have been applied to theoverlapping attached portions of the hinge strips; and a` second meansfor applyingsealing pressure to ensure the even attachment of the endleaves to the hinge strips.A

The table for supporting the several elements is denoted by I2. Themagazine I3 serves as a means for supplying successive book bodies. Thelongitudinally disposed endless carrier I 4 is arranged to receivesuccessive book bodies from the magazine I3 and intermittently advancethe book bodies along the table I2. A magazine I5 serves as a source ofsupply for the foldedend sheets.Y Y Y The means for simultaneouslyapplying gum to the outer`faces of the leaves of the folded end sheetsalong the desired portions thereof is herein shown as agummervlcomprising upper Vand lower gumming rollers II and I8-andtheirgum supply fountains I9 and 20. The narrow upper roller I1 is shownas adapted to gum a narrow band on the outer face of one leaf of afolded end sheet and the wide lower roller I8 is shown wide enough togum a wide band on the outer face of the other leaf. A scraper 2| may beused in connection with the wide roller I8 to control the widthvk of theband of gum applied thereby. For instance, the two gumming rollers whenused without the scraper are arranged to gum the outer faces with narrowand wide bands lupon opposite sides of the folded edgeof a middle foldedend sheet. Where the scraper 2| is used in connection with the widelower gumming roller I8, narrow bands may be gummed on the outerr facesofthe. two leaves of an off-middle folded end sheet at their free edges.

The means for folding the free edges of the hinge strips over onto theexposed gummed portion rof the upper leaf of the folded end sheet afterthe gummed portion of the lower leaf has beenv adhered to theoverlapping `portion of the hinge strips byL the operator, is shown ascomprising a folder bar 22 manually operated from a foot lever 23suitably placed for the convenience ofthe operator.

The means for applying sealing pressure to the attached portions of theend sheets and hinge strips may comprise a series of pairs of pressurerollers 24, 24. between which the book bodies with their attached endleaves are passed, to ensure aneven'sealing of the end leaves to thehinge strips. Where the end sheet applying operations are tov berepeated by duplicate apparatus in the same machine wepreferably providea hinged plate 25onto which the book bodies are are successively pushedby their preceding book bodies. The hinged plate 25 may be swung toreverse'` the books as follows: a spring pressed tripping nger 26projects in position to be operated by the leading book body as itarrives on the reversing plate 25, thus forcing the nger away from' itsnormal position and thereby bringing its rotating clutch member 21 intoengagement with the normally idle clutch member 28 which may be providedwith a rotary segment 29 adapted in its rotary movement to mesh with asegment 3U on the hinge of the reversing plate 25 and thus swing theplate upwardly and over a sufficient distance to reverse the book bodyand deposit it on a laterally disposed endless carrier. The plate may bereturned to its normal horizontal position by the weight 3| and itsconnection 32 as soon as the segment 29 leaves the segment 30. As soonas pressure is released from the tripping finger 26 the finger willreturn to its normal position and its rotating clutch member 2'Iseparated from the clutch` member 28.

,A laterally disposed endless carrier is denoted f by 33 and it isarranged to convey the reversed book ybodies laterally into position tobe engaged and advanced by a second longitudinally disposed endlesscarrier 34. The reversed book body may then be subjectedto the end sheetapplying operations by the use of the second folded end sheet supplymagazine 35, the second gummer 36, the second folder 31 and the secondsealing pressure means 38.

A common drive, such as a motor 39, may be provided for operating thefirst and second longitudinally `disposed endless carriers, thelaterally disposed endless carrier, the first and second gummers, thefirst and second pressure applying means and the bock body reversingmeans.

In the present instance the motor 39 is shown as operatively connectedto the first longitudiaesaif 3 49. This motor 39 is shown as operativelyconnected to the second longitudinally disposed endless carrier 34 bythe double pulley 40, belt 50,

pulley 5I, cross shaft 52, bevel gears 53, 54, shaft 55, bevel gears 55,51 and shaft 58.

The motor 39 is shown as operatively connected to the first gummer i6through the pulley 59, cross belt 60 and pulley 6| on the cross shaft 62of the lower wide faced ugumming roller I8 which may drive the uppernarrow gumming roller I1 through the gears 63, 64.

The second gummer 36 may be driven from the cross shaft 52 through thepulley 65, belt 66 and pulley 61 on the shaft of the lower wide facedgumming roller I8.

The lower rollers 24' of the first sealing pressure means may be drivenfrom the cross shaft 52 through the train of gears 6B. Similarly, thelower rollers of the second sealing pressure means 38 may be driven fromthe cross shaft 43 through the train of gears 69. The laterally disposedendless carrier 33 may be driven from the cross shaft 52 through thebevel gears 10, 1I, shaft 12, spur gears 13 and shaft 14.

The clutch member 21 of the book body reversing means may be driven fromthe shaft 14 through the train of gears 15.

A floor guide 16 may be provided for turning the free portion 3 of theupper hinge strip upwardly into position to be engaged and turned overby the manually operated folder bar 22.
